NSI-MI Technologies EIRP Analysis software computes the Equivalent Isotropically Radiated Power (EIRP) of a transmitting antenna. This measurement capability offers several choices in obtaining a peak level EIRP with the option of normalizing any number of multi-axis scans. These choices are available to accommodate the many different test setups and preferences that may be encountered. The combination of this analysis and the NSI-MIs Arena data collection and sequencing capability comprise a complete EIRP measurement capability.
Far-Field EIRP Analysis
Supported far-field measurement techniques:
- A spectrum analyzer or power meter is used as the receiver with a standard gain horn (SGH) as the receive antenna. The range length and losses for both transmit and receive must be known.
- The AUT is used to transmit to the SGH as the receive antenna and the normal system receiver is used to measure the received signal. A power meter is used to measure the transmit power level before the AUT. The range length is not needed for this technique.
Near-Field EIRP Analysis
Supported near-field measurement techniques:
- A spectrum analyzer or power meter is used to measure the transmit power level and the AUT transmit data is collected with the system receiver.
